In the loess-filling project, original structural loess under filling will produce creep deformation isometric consolidation stress state, affecting upper building’s safe construction and later operation. Therefore, studying characteristics of different coefficients is significant. this paper, following results are obtained by combining test theoretical analysis. view filling, triaxial undisturbed coefficients, confining pressures shear levels was completed, law obtained. The found to be...
Active substances such as asphaltene and resin in heavy oil tend to absorb on the oil–water interface. Thus, water would easily emulsify into water-in-oil (W/O) emulsion under shared action of formation porous media. Emulsification produced fluid during recovery is important for accurately calculating recovery. Studies properties can effectively forecast reservoir production dynamics. Therefore, water/steam flooding experiments at different permeabilities, viscosity, varying temperature were...
Abstract The stability of surrounding rock with bolt support depends on the within reinforcement range. To understand reinforcing mechanism a rectangular roadway fully and accurately, quantitative method for evaluating must be developed. First, roof beam model tunnel is established according to deformation law rock. Based elastic–plastic theory, deflection calculation formula can derived, ultimate load obtained under plastic state without support. Second, based effect bolts, body...
Abstract With the increasingly stringent national environmental rules, waste produced in drilling and completion process is forbidden to be discharged into Bohai Bay or reinjected formation. The current disposal method of Oil field has some problems such as high cost, low efficiency HSE management control risk. Faced with these problems, reutilization zero discharge technology been developed applied this region. In order reutilize which include cuttings circulated from formation, wasted...
Horizontal well water coning in offshore fields is one of the most common causes rapid declines crude oil production and, even more critical, can lead to shut down. The Y field with a cut 94.7% urgently needs horizontal control. However, it challenge for polymer gels meet requirements low-temperature (55 °C) gelation and mobility control wider range. This paper introduced novel gel cross-linked by hydrolyzed polyacrylamide chromium acetate phenolic resin well. detailed gelant formula...
It is very important to process acid and fracturing treatment in oil field improve permeability. The pump one of the key equipment for Acid treatment. valve box fundamental, costly wearing parts. Based on data from domestic abroad, life short. Fatigue cracks caused by alternating stress erosion account most invalidation box. Only increasing structural size improving material property are not efficient prolong service life. Related studies show that hydraulic self-enhancement technology an...
Rock bursts are sudden instability phenomena of a coal mass that occur under the superimposed action dynamic and static stresses. Current research on mechanism rock primarily focuses inherent properties coal-rock masses. However, there have been few studies effects stresses characteristics roadway structures. Therefore, this study initially introduces concept key block burst conditions, simplifies external disturbances into plane stress waves, establishes mechanical model for combined The...
In order to identify the content of various heavy metals, soils farmland surrounding Huashan's gold tailing mine are studied. Surrounding soil samples collected in new and old mines. Flame atomic absorption spectrometry is taken measure Pb, Zn, Cd, Cr, Cu. addition, method combining Geo-accumulation index potential ecological risk applied evaluation pollution soils. It able provide technical basis environmental management recovery this region. The results show that: (1) Cu most important,...
In this paper, the surface water and sediments of gold mining area in Xiaoqinling, Puyugou were taken as research objects to investigate enrichment heavy metals. Contents various metals tested systematically. The osculating method index's pollution metal used together evaluate analyze test results. results can provide technical reference for environmental restoration governance. show that there is a small mount Cu Zn upstream which not affected by activities. It indicates have been polluted....
As a convenient, efficient, secure and high working quality casing running tool, the top drive tool (CRT) has been recognized by enterprises users of petroleum mechanism instrument. Slips system is an important subassembly CRT, which directly decides reliability, security surface while or drilling with casing. Based on finite element method contact mechanics, research model CRT's slips established influence studied. The effects front angle, bottom angle teeth interval interface are analyzed....
Top drive casing running tool, because of its convenience, speed and safety, has been widely received by the research enterprises petroleum mechanism instrument. Now, there have developed several kinds tools which gradually used drilling corporation at home abroad. The slips system’s parameters, such as axial thrust, length, teeth form, interval, etc., directly affect performance safety tools. Those no reports about correlative theoretical investigation results. Here, we found mechanical...
Marginal oil fields refer to some small and medium-sized or with complex stratigraphic structure located in remote areas. There are more than 100 large blocks marginal huge reserves. They have the characteristics of geological reservoirs such as structural fracture, fault development reservoirs. The is uncertain not suitable for excessive investment. How carry out economic effective exploration has become a new breakthrough stabilizing production improving benefits A oilfield, first field...
