As for production contradiction exposed in late high water-cut period of Tuha low permeability and viscosity oilfield,in order to further improve development level of old oilfield,secondary development framework plan of Tuha oilfield is worked out.

Study and application of acid-fracturing for increasing injection in Duanliubo low permeability oilfield;

A reasonable development strategy of sandstone reservoirs with abnormal high pressure and low permeability;

Interlayer interference for low permeability thin interbedded reservoirs is becoming more and more serious in JS Oilfield.

Clinical Study of Regional Infusion Combined with Hypotonic Intraperitoneal Chemohyperthermia for Prevention of Recurrence and Metastasis after Radical Resection of Gastric Carcinoma;

Clinical study on therapy of malignant ascites from gastrointestinal tumors by intraperitoneal chemotherapy through hyperthermal and hypotonic liquid perfusion;

Objective To investigate the clinical effect and value of hypotonic intraoperative intraperitoneal chemohyperthermia(HIPCH) in advanced gastric cancer.

An application of NMR logging to calculating permeability in low porosity and low permeability reservoir;

According to membership function and maximum subordination principle,this paper establishes a mathematics model to identify fluid in low porosity and low permeability area by using seven basic reservoir parameters with different weight.

In the studied area, the reservoirs, which buried deeply with strong compactness, belong to typical low porosity and low permeability reservoirs.

In order to evaluate the reservoir oil-bearing property effectively and get accurate water saturation,many rock-electricity experiments are carried out in different strata and sandstone reservoirs with low porosity and permeability of different lithology.

Research and application of cementing technologies in low pressure and low permeability reservoirs in Daniudi gas field;
