Particle void filling effects (Pf) under low pressure and coal matrix compressibility (Pc) at high should not be ignored when using mercury intrusion porosimetry (MIP) to study the pore size distribution of coal. In this study, two samples (FX HF) collected from western Guizhou were crushed into three different grain sizes; then, subsamples analyzed by MIP low-pressure nitrogen adsorption characteristics. The micro- transition volumes contribute total volume FX HF subsamples. With decreasing...
Abstract The overseas oil and gas investment evaluation is one of the core tasks in companies, among which risk benefit are most important. This paper sets forth transmission paths factors to by identifying 14 risks four categories. On basis concept compensation, different compensation mechanisms specific each designed. integrated objectively develop a comprehensive model correcting recoverable reserve, adjusting parameters such as investments on exploration development, compensating for...
In the complex fracturing process of shale gas wells, casing is subjected to serious deformation, which can easily failure wellbore integrity and reduction well construction productivity. It particularly important clarify deformation mechanism carry out effective control. Based on logging data from full-scale indoor tests, mainly considered be shear non-uniform extrusion caused by formation slip displacement control, i.e., ultimate working conditions. The boundary (<40 mm) under...
Liquefied natural gas (LNG), recognized as the fossil fuel with lowest carbon emission intensity, is a crucial transitional energy source in global shift towards low-carbon energy. As industry undergoes rapid expansion, complexity of investment business models has increased significantly. Optimizing combination various segments within value chain become standard practice, making it essential to control risks and enhance economic benefits these multifaceted scenarios. This paper introduces an...
In this paper, a two-axis compensation device was designed to eliminate the impact of attitude deviations moving platform on laser point cloud. order improve dynamic performance device, fuzzy proportional-integral differential (PID) controller employed for device. Then, semi-physical simulation experiment carried out quantitatively evaluate using three-axis turntable and high-accuracy inertial measurement unit (IMU), which used measure in real time. As result, roll pitch measured by IMU can...
In field hydraulic fracturing operation of shale gas development, the high pressure and large displacement liquid-particle two-phase fluid can be forced to change direction many times through high-pressure double-elbow, transported from outlet pipeline pump main pipeline. The double-elbow is prone affected by erosion wear Fluid-Structure Interaction (FSI), resulting in perforation fracture, posing a potential safety threat operation. this study, we conducted experiments on 35CrMo steel used...
The CO 2 displacement is one of the gasflooding Enhanced Oil Recovery (EOR) methods. application from volatile oil to black popular mainly because requires a relatively low miscibility pressure, which suitable most reservoir conditions. However, always contains some impurity, such as CH 4 , H S and N leading change phase behavior flooding efficiency. Whether achieves successfully miscible depends on pressure temperature, injected solvent crude compositions. So three different types samples...
Abstract This paper focuses on the strain based design and field application of thermal well casing for cyclic steam stimulation process. The heavy oil is a main China petroleum industry, where process has been widely used playing dominating role in production. Generally damage rate 15-30% under this process, which resulted large economic cost. high mainly caused by current strength method, both room elevated yield were considered not beyond anticipated stress. In fact material will serve...
In the increasingly complex environment of downhole working conditions such as frequent opening and closing oil gas wells, acidification/multi-stage fracturing, steam huff puff, strong injection production, traditional casing string design method standards based on strength have gradually highlighted their limitations. It is necessary to formulate that consider full life cycle wells drilling completion, production operations. Starting from analysis advantages disadvantages methods, this...
In this paper, an integrated workflow was developed to estimate coalbed methane (CBM) probabilistic resources. This captures all of the uncertainty parameters in CBM modeling, including structural surface and coal thickness modeling facies, logging density, etc. property modeling. These uncertainties were statistically analyzed quantified. Sensitivity analysis carried out rank impact these on resources, six sensitive chosen. Then, multiple stochastic models generated using aforementioned...
Abstract The low-temperature nitrogen adsorption measurement is commonly used to describe the pore structure of porous medium, while role degassing temperature in does not attract enough attention, various temperatures may lead different characterization for same coal. In this study, low-rank coal collected from Binchang mining area, southwest Ordos Basin was launched under seven (120 °C, 150 180 210 240 270 °C and 300 °C), respectively, dynamic change refined upgrading are studied, it also...
Abstract This work deals with the design and application of a seafloor sediment corer novel hydrostatic motor. The motor uses seawater pressure energy as power for penetration by corer. It is automatically triggered mechanical linkage when lands on seafloor, enabling to accomplish an initial gravity before activated. As key feature motor, hydraulically actuated valve employed control transfer ambient high-pressure vacant chamber. Driven transfer, head continuously repeats movements lifting...
