Abstract

Abstract

When working over wells with low pressure reservoirs, loss of workover fluids into the reservoirs has long been a problem that needs to be resolved. A double crosslinked foam gel well killing fluid has been developed for the resolution of this problem. The basic composition of the killing fluid is:3% polyacrylamide + 2% foaming agent + 1.5% crosslinking agent A + 0.1% crosslinking agent B. It was found under microscope that single crosslinked foam gel and double crosslinked foam gel all had obvious dualmembrane structure, the double crosslinked foam gel had thick and tough membrane. The thickness of the membrane surrounding the gas core of the foam was 77.35 μm (max.) and the total thickness of the membranes surrounding the gas core was 188.48 μm (max.). The thick membranes render the foam gel high compressive strength and good stability. The foam gel can stay stable for at least 10 d, far longer than single crosslinked foam gel. Rheology and viscoelasticity test of the foam gel showed that the double crosslinked foam gel had high elasticity and low viscosity, making it easy to be pumped and flowed back. Simulated temporary plugging well killing experiments showed that for cores with porosity between 90 mD and 208 mD, pressure drawdown across the cores under 2 MPa positive pressure differential was less than 0.05 MPain 60 min, and the rate of filtration of fluid through the cores was almost zero. These data showed that the double crosslinked foam gel well killing fluid has a certain compressive capacity and low filtration rate, and can effectively plug reservoir rocks temporarily, rendering it good application prospects in preventing loss of workover fluids in low pressure reservoirs.
