Lateral Horizontal Well Research And Application In The LENG-42

The multilateral horizontal well technology is a new technology following the horizontal well and branch well, has broad development prospects. The research based on to the branch horizontal well's fundamental research, the laboratory experiment studies, the field test research, the engineering technology research as well as the branch horizontal well in the LENG 42 application condition investigation and study, has induced the branch horizontal well predominant type, the characteristic, summarized the branch horizontal well technical aspect and the progress. through analyzed the Liaohe oil field LENG 42 branch horizontal well the application condition and the development effect, summarized the branch horizontal well suitable condition as well as the question which and the limitation existed in the fundamental research and the field application aspect, based on to the branch horizontal well fundamental research condition, the experimental study condition, the scene experimental study condition, the engineering research condition and so on investigation and study, has induced the branch horizontal well type, the characteristic, increased production the mechanism, the engineering design principle as well as drills the well completion essential processing technology, produced can calculate the forecasting technology, the technique of production technology and so on, has made the massive field application investigation and study in view of the Liaohe oil field LENG 42 sub-area branch horizontal well application situation, the analysis The branch horizontal well technology's serviceability and the limitation, as well as in studied the question which and the limitation and in the application existed, and has carried on the forecast to the development direction and the prospect, has provided the theory basis and the instruction function for the branch horizontal well technology's research. the branch horizontal well the dead area which and the garret oil, the lens oil gas pool creates in the development water cone, the thin layer oil gas pool, pulls down the seepage oil deposit lowly,"aquatic floats"the oil deposit, the macro viscosity thick oil deposit, the penetration coefficient needs the water drive differently the reservoir, the high directionally permeable reservoir, has many group of intrinsic fracture oil gas pools, the compact sandstone oil gas, the natural asphalt oil deposit, aspects and so on excavation remaining oil have made the remarkable progress, has become the oil-gas field development one kind of important vanguard technology, will obtain more and more widespread application.
