0.前言塔河油田的油藏特点是油稠、埋藏深,目前采用电泵环套搀稀、皮带机配合小泵深抽等机采方式,阶段性满足生产需要,但随着地层能量的下降、以及温度、硫化氢等的影响,现在的机采工艺已经优化到接近极限,为此必须立足于发展的角度找寻一种适合稠油深抽的机采工艺。1.机采工艺优化分析塔河油田的井况具有两超即超深、超稠,五高即高粘、高温、高压、高硫化氢、高矿化度的特点。原油为高粘度、含蜡、高含硫的超重质原

Introduction Tahe oilfield reservoir characteristics of oil thick, deep buried, the current use of thinning pump sleeve, belt machine with a small pump deep pumping machine mining methods, stage to meet production needs, but with the formation of energy Decline, and temperature, hydrogen sulfide, etc., the current machine mining technology has been optimized to near the limit, for which must be based on the development of a search for a heavy oil deep pumping machine mining process. 1. Optimization of machine mining technology The well conditions of Tahe Oilfield are characterized by two super-ultra-deep, super-thick, five-high, high viscosity, high temperature, high pressure, high hydrogen sulfide and high salinity. Crude oil is a highly viscous, waxy, high-sulfur, ultra-heavy, plastid
