Calculation method for dynamic fluid loss of acid-etched fracture considering wormhole propagation
23 Sep 20
The invention discloses a calculation method for dynamic fluid loss of acid-etched fracture considering wormhole propagation, which is applied to pad acid fracturing process, comprising the following steps: Step 1: dividing the construction time T of injecting acid fluid into artificial fracture into m time nodes at equal intervals, then the time step Δt=T/m and tn=nΔt, where, n=0, 1, 2, 3, . . . , m, and to is the initial time; Step 2: calculating the fluid loss velocity vl(0) in the fracture at t0; Step 3: calculating the flowing pressure distribution P(n) in the fracture at tn; Step 4: calculating the width wa(n) of acid-etched fracture at tn; Step 5: calculating the wormhole propagation and the fluid loss velocity vl(n) at tn; Step 6: substituting the fluid loss velocity vl(n) into Step 3, and repeating Step 3 to Step 6 in turn until the end of acid fluid injection.

Method for Lowering Oil Pipe In Gas Well without Well-killing, Soluble Bridge Plug and Material Preparation Method Thereof
5 Feb 20
The present invention discloses a method for lowering an oil pipe in a gas well without well-killing, a soluble bridge plug and a material preparation method thereof, wherein, the method comprises the steps of: lowering a bridge plug in a wellbore such that the bridge plug blocks the wellbore at a predetermined location in the wellbore; injecting water in the wellbore after the pressure in the wellbore has been relieved so as to replace gases in the wellbore; and lowering an oil pipe in the wellbore to the location of the bridge plug.
