The design trajectory parameters of 3D horizontal wells in X gas field are not uniform, the construction is random, and lack standardization enough to achieve rapid drilling. Based on analysis data difficulties completed well, according different types, by standardizing drilling tool assembly well design, making full use characteristics formation law, using supporting tools control sand carryin...

The SD107 gel system developed has good oil–water phase selective gelation and blocking properties. static gel-forming experiment results showed that the water shutoff formulated with oilfield reinjection (oil content < 0.05%) a viscosity of 200 mPa·s after gelation, plugging produced fluid ? 20.0%) had 26 gelation. Results core physical simulation indicated enhanced recovery rate was highes...

The southern part of Jin45 fault block is a low permeability layered reservoir with thin oil layer thickness. And the development horizontal well pattern has good economic benefit in block. distribution quite different. main stable, but non-main unstable. In this study, through engineering method and numerical simulation method, direction, form, spacing length are optimized to determine layer. ...
