With the deepening of drilling depth, difficulty engineering increases gradually due to complex geological conditions. The traditional mechanical method shows problems high energy consumption, low efficiency, long cycle and cost. Because characteristics rock, abrasiveness rock causes great wear bit, which becomes an important factor affecting rate. High voltage electric pulse (Abbreviated as HVEP later in this paper) technology is a new developed past several decades. uses plasma channel,...
The sulfide stress cracking (SSC) behavior of three micro-alloying 110 ksi grade Cr-Mo casing steels were evaluated according to the A-Method tensile test specified in NACE TM0177 standard (NACE A-method). fractures SSC specimens and micro-structures characterized by scanning electron microscopy (SEM) with backscattering diffraction (EBSD) transmission (TEM) BF STEM mode. results show that on premise ksi, yield strength Co-Mo steel was satisfactory, finer spherical carbides increased number...
Unconventional oil and gas reservoirs, characterized by low porosity permeability, often require multistage fracturing techniques for development. The high-pressure fluids with large volumes can easily cause alternating changes in both temperature pressure within the casing. Using a theoretical model field data from hydraulic operations, this paper calculated ranges of axial loads temperatures reservoir section. Based on calculation results, temperature–load coupling test P110 casing was...
Summary To solve the problem of annular gas channeling in natural well cementing, isoprene rubber was used as graft matrix material, absorbing methyl methacrylate and octadecyl acrylate were functional monomers, a gas-inspired expansion polymer prepared by copolymerization, gas-triggered self-repair cementing slurry developed. The structure gas-sensitive grafted characterized Fourier transform infrared (FTIR) 1H nuclear magnetic resonance (NMR), effects monomer concentration copolymer feed...
The opening of the Ice Silk Road is a great significant for realization close connection with European, and it promotion China's economic development. icebreaker will play an important role in Arctic strategy. More accurate ice load calculation prediction breaking capacity methods provide technical support design construction icebreaker. This paper aims to solve above problems carry out following research work. continuous icebreaking type calculated 3D numerical method. Then, motion...
Calcite cementation is one main cause for reduction of porosity and permeability. In the case Chang 6 Member Jiyuan Oilfield, calcareous interbeds have been investigated characteristics genetic mechanisms within delta-front oil reservoirs so as to reveal their spatial distribution. As shown by research, carbonate content in this area more than 10% will significantly reduce reservoir permeability, well its oil-bearing property. vertical, are commonly developed at interfaces, where mudstone...
