Embodiment 1
[0043] Example 1 The following components are used to prepare solid-free positive drilling fluid, perforating fluid, well flushing fluid, fracturing fluid, spacer fluid or gravel packing fluid:
[0044] 1% cationic polyacrylamide (CPAM)
[0045] 2% cationic starch (NCP)
[0046] The balance is water.
[0047] Wherein the cationic polyacrylamide, cationic starch and water are added into the reactor at room temperature (25° C.), and stirred thoroughly to obtain an aqueous composition.
Embodiment 2
[0048] Example 2 Add 0.5% aluminum chloride as an electrical stabilizer to the formula in Example 1, and use the same method to prepare solid-phase positive drilling fluid, perforating fluid, well flushing fluid, fracturing fluid, and spacer fluid or gravel pack fluid.
Embodiment 3
[0049] Example 3 Add 0.3% xanthan gum as a colloidal stabilizer to the formula in Example 2, and use the same method to prepare solid-free positive drilling fluid, perforating fluid, well flushing fluid, fracturing fluid, spacer fluid or gravel pack fluid.
