鄯勒油田煤系地层注水开发适应性研究

鄯勒油田是吐哈油区的一个特低渗煤系互层油藏，地质条件特殊，构造复杂。针对煤系地层注水保持地层压力开采可能存在的问题进行了研究，从地质及工艺的角度对注水可行性进行了论证；注水实践，在同井组油井见到成效，为鄯勒油田能否注水开发提供了最直接的依据，也为国内同类煤系地层的开发提供了宝贵的经验和第一手资料。

Study on adaptability of coal measure strata in Shanle Oilfield

Shanle Oilfield is the especially low permeability oil reservoir of coal measure interlay in Tuha oil region,with particular geologic condition and complicated structure.Because of depletion type of exploitation in early period,the reservoir pressure has been keeping on decline since putting into production.The crude output has been declining distinctly and the producing energy is in dire need of supplementary.The paper starts with the questions of coal measure strata developed by water flooding to maintain producing energy.Great deals of experiments and research have been carried through,and sufficient demonstration to the feasibility of coal measure formation waterflooding has been conducted from the point of technics.On the base of above work,the J2x formation in Shanle Oilfield coal measure strata has been carried out waterflooding practice.The oil wells in the same well group take on good effect,which offers the most direct evidence for the feasibility of water flooding development in Shanle Oilfield and provides valuable experience and firsthand information for congener coal measure strata.
